Jyotish Yogas (吠陀瑜伽組合)

The Named Planetary Combinations at the Heart of Vedic Judgment

Overview

In Jyotish, a Yoga is a named planetary combination — a specific arrangement of planets, signs and houses that classical texts recognise as producing a particular result. Yogas are the true heart of Vedic chart judgment: a Jyotishi reads a chart not planet by planet but by the yogas it forms. This endpoint reads the full nine-graha sidereal chart (the seven classical planets plus the lunar nodes Rahu and Ketu) placed in whole-sign houses from the Lagna, and detects the FIRM, universally-agreed yogas — the ones every major text defines the same way and a program can check without interpretation. It deliberately leaves out the hundreds of low-agreement minor yogas whose definitions diverge from book to book, so what it returns is trustworthy rather than merely long.

Origin & history

The yoga literature is spread across the foundational texts of Jyotish. The five Pañca Mahāpuruṣa (‘great person’) yogas and the Moon-based yogas (Sunapha, Anapha, Durudhura and the difficult Kemadruma) are set out in Saravali (Kalyanavarma) and the Brihat Parashara Hora Shastra; Phaladeepika (Mantreswara) gives the Vipareeta Rāja and Neecha Bhaṅga rules in their cleanest enumerated form; and B.V. Raman’s twentieth-century ‘Three Hundred Important Combinations’ is the standard modern compendium (and the firm source for Budhāditya and Chandra-Maṅgala). askTIAN’s engine follows the firm core of these sources and is candid about where texts diverge.

Because yogas accumulated across many centuries and authors, the same name can carry slightly different rules in different books — which is exactly why askTIAN reports only the combinations that are stable across sources, each tagged with its provenance. The exaltation degrees and moolatrikona ranges are the Brihat Parashara Hora Shastra values (Ch. 3). The Pañca Mahāpuruṣa trigger is own-sign-or-exaltation in an angle from the Lagna (the kendra-from-Moon reading and moolatrikona-as-trigger are noted as source-divergent and left off). Kemadruma excludes the Sun and the nodes from the isolation test (the mainstream convention). Neecha Bhaṅga is reported as a full Rāja Yoga only when the freed planet actually rules an angle or trine — cancellation of a debilitation is not, by itself, a rise-to-power signature. The whole engine is gold-locked against B.V. Raman’s published chart of Jawaharlal Nehru: it reproduces all nine planetary signs, reads Mars as the yogakāraka, and correctly finds NO Gaja Kesari.

How it works

Give a birth date, time and place. The engine computes the nine grahas on the Lahiri-sidereal ecliptic (the same ephemeris as the Jyotish and Ashtakavarga endpoints), places each in its whole-sign house from the Lagna, and works out each planet’s dignity (exalted / own / moolatrikona / debilitated / friend / neutral / enemy), retrogression and combustion. It then runs the firm-core detectors: the five Pañca Mahāpuruṣa (Ruchaka, Bhadra, Haṃsa, Mālavya, Śaśa), Gaja Kesari, Budhāditya, Chandra-Maṅgala, Rāja Yoga (a single yogakāraka lording both an angle and a trine, plus distinct angle-lord/trine-lord links by conjunction or mutual aspect), Dhana (wealth-house lords linked), Vipareeta Rāja (Harṣa/Sarala/Vimala), the difficult Kemadruma (with its cancellation), and Neecha Bhaṅga. Each detected yoga comes back with the exact rule that fired, its classical significance, a strength (strong / moderate / qualified), a benefic/malefic/mixed polarity, and a provenance note. Yogas are judged from the houses, so the endpoint needs a birth time — without one it returns the grahas but no yogas, and says so.

Good for

Use cases

Yoga Scan of a Birth Chart

Send birth data and receive every firm-core yoga the chart forms, each with the planets and houses that make it, its strength and its meaning — the yoga layer a Jyotishi reads first.

Pañca Mahāpuruṣa Check

See whether Mars, Mercury, Jupiter, Venus or Saturn sits in an angle in its own or exaltation sign — the crisp ‘great person’ signatures (Ruchaka, Bhadra, Haṃsa, Mālavya, Śaśa).

Rāja & Dhana Yogas

Find the chart’s yogakāraka and the angle-lord/trine-lord links behind status and success, plus the wealth-house links behind income and gains.

Honest Reading of Difficult Yogas

Kemadruma and a debilitation are reported with their classical cancellations, so a challenging signature is never overstated — a cancelled Kemadruma or a neutralised debilitation is flagged as such.

Key terms

Yoga
A named planetary combination — a specific arrangement of planets, signs and houses that classical Jyotish recognises as producing a particular result. The core unit of Vedic chart judgment.
Kendra / Trikona
The angles (houses 1, 4, 7, 10) and the trines (1, 5, 9). Their lords, and planets placed in them, drive most benefic yogas; a planet ruling both an angle and a trine is a yogakāraka.
Pañca Mahāpuruṣa
The five ‘great person’ yogas — Ruchaka (Mars), Bhadra (Mercury), Haṃsa (Jupiter), Mālavya (Venus), Śaśa (Saturn) — formed when that planet is in an angle from the Lagna in its own or exaltation sign.
Yogakāraka
A single planet that rules both an angle (kendra) and a trine (trikona) for a given ascendant — the strongest Rāja-yoga signature (e.g. Mars for Cancer and Leo lagnas, Saturn for Taurus and Libra).
Kemadruma
A difficult yoga: the Moon isolated, with no planet (excluding the Sun and the nodes) in the 2nd or 12th from it, nor conjunct it. Very often cancelled (bhaṅga) — the engine reports the cancellation when present.
Neecha Bhaṅga
The cancellation of a planet’s debilitation — through its dispositor or the sign’s exaltation-lord sitting in an angle, or the dispositor aspecting it. Reported as a Rāja Yoga only when the freed planet rules an angle or trine.

API

The askTIAN Jyotish Yogas endpoint reads the full nine-graha Lahiri-sidereal chart in whole-sign houses and detects only the FIRM, universally-agreed classical yogas: the five Pañca Mahāpuruṣa, Rāja (yogakāraka + angle/trine links), Dhana, Gaja Kesari, Budhāditya, Chandra-Maṅgala, Vipareeta Rāja, the difficult Kemadruma (with its cancellation), and Neecha Bhaṅga. Each yoga returns the exact rule that formed it, its classical significance, a strength (strong / moderate / qualified), polarity and source-provenance (BPHS / Saravali / Phaladeepika / Raman) — and the hundreds of low-agreement minor yogas are deliberately out of scope. Gold-locked against B.V. Raman’s published Nehru chart (all nine signs reproduced, Mars as yogakāraka, Gaja Kesari correctly absent). Yogas are judged from the houses, so a birth time and place are needed for the Lagna; without them the grahas still return. A best-effort LLM reading is provided in parsable sections (set interpretation:false for structured data only). Symbolic classical framework for reflection — not a validated predictor, and not medical, legal or financial advice.
